Alright thanks. But if it were discovered.... How much of an impact do you think it would have?

There's no empirical answer to your question. We don't know how much of an impact. However, if it had a big effect we would see more variance on lsn. There are likely minor errors in many applications, and yet admissions numbers are not that inconsistent.

I agree that it's not likely to have much of an effect, but I also doubt that Harvard is dinging very many high scorers for yield protection. Rather, they're one of the few schools with enough high-quality applicants that they can afford to look beyond the numbers and make decisions based on softs, without worrying about their medians.

Improbably enough, this exact thing happened to me (typo in the final paragraph of my PS to HLS, where I was a fringe candidate). I sent in a fresh version and got in. No clue if it helped. My opinion: Might as well send in a fixed copy.
